Wikipedia (in German) lists all graves of famous writers, philosophers, poets and members of the German resistance that can be found here. There is one mistake about this burial ground: W. Biermann wrote about this place as “Hugenottenfriedhof”. But the real burial ground with this name is to the south-east of Dorotheenstaedtischer Friedhof. Moreover, don’t mix up this burial ground with ”Dorotheenstaedtischer Friedhof II“. This extension of the burial ground can be found in Liesenstrasse, not in Chausseestrasse.
A tiny cafe behind the chapel of this burial ground can be recommended: nice cakes and a lot of books are on display that are related to the people of this burial ground.
